Strange Bedfellows

I saw this bumble bee recently fast asleep in a dahlia bloom.  He was very content and not bothering anyone.

This yellow jacket on the other hand, found it's way into our bedroom and under our covers and it wasn't very content as I found out when it stung me.  I didn't know what exactly what was going on when I first felt the pain on my leg but as it got worse I realized that something was biting me and threw off the covers.  HWNSNBP had been asleep for some time as he goes to bed long before I do and when I turned on the light he asked groggily what I was doing.  When I explained that I had been bit by something he told me to just get back in bed.  I briefly saw the culprit on our navy sheet but when I went to grab a tissue it disappeared.   But I could hear the angry buzzing somewhere near.  My leg was throbbing by this time and I will admit there were tears.  I told him that I was not getting back in that bed and we both went downstairs to sleep on the couch and love seat which I'm glad we chose to do as I found another dead one on the floor in the other bedroom the next day.   When we woke up the next morning he went upstairs and as I thought might be the case, the yellow jacket had been attracted to the light and was on the window where HWNSNBP was able to get it.  Of course we're wondering where it (they) came from.  He had come across a nest in an outlet on the front porch which is below our bedroom a couple of days prior and had sprayed it to get rid of the buzzers.  Did they come up through the wall or someplace else?  Hopefully we've seen the last of them but I am still getting into bed with trepidation.  I thought spiders were all I had to worry about.
